Question

.Which of the following is the equation of a line parallel to the y-axis?​ y = 0
x + y = z
y = x
x = a

Answer 1

Answer:

here is your ans

Step-by-step explanation:

Thus, if P(x, y) is any point on AB, then x = a. Hence, the equation of a straight line parallel to y-axis at a distance a from it is x = a. The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it.

Answer 2

Option (d) x=a is the correct answer. It is parallel to the y- axis.

Solution: When a line is parallel to y-axis, the value of y-coordinate keeps changing. Its value of y coordinate can range from -∞ to +∞.

The x-coordinate is constant for the line. If the x-coordinate changes, the line will no longer be parallel. It will be a skew line.

In x=a, a is a constant number which shows that this line is parallel to the y-axis.
